Looking thru 250, going to 250.53 (D)(2) Exception leads some to believe what you describe as being compliant. However, reading the exception, it refers to 250.52 (A)(1) exception, which states 'industrial, commercial, and institutional structures....' So based on that I will lean towards a "NO".
The 'split bolt' also is a NO, as the connections should be irreversable. IMHO!
But, let's see what others say!
